There's a couple of ways they could go about resolving this:
1. Restrict Novices from using RODEX. Once they job change, RODEX will become accessible.
2. Implement a job class restriction on Dead Branches and Bloody Branches. Have them usable by every job class except Novices.
A level cap won't work because dedicated griefers could easily leave a character in the Training Grounds to level to whatever cap is implemented for the branches. And I'm pretty sure there will be people who would be upset at having a Level 100 restriction on branches.
Supernovices and generally overleveled novices are a thing. Some players like to play those. So restricting by class isnt the best solution either. Making RODEX unavailable in training grounds is a better solution, imo.
